[QUOTE="Jamie6.5, post: 297850, member: 16954"] If you want to stay with the .270: The advice here on bedding/truing/floating etc. is all good, but!! Start working up a load with the higher BC 150gr bullets. Better retained velocity. Find out how deep YOUR rifle's throat is and tweak the COL until you find which depth yours likes, and hope it will fit in the magazine. Many factory .270s are throated to accept the 160gr round nosed slugs and have throats that are way deeper than practical. This is probably contributing to your 2" groups (with 130gr?) @100. Some bullets/loads like to jump, others don't. Then if you find you're not getting the velocity/accuracy combo out of it you want, you might try having the chamber Ackley'd. Then you get to start over on your load workup. If you do rebarrel, I agree with the above, go with the .280AI. [/QUOTE]
